class="title">詳細(xì)說明</p><div id="77b9znl" class="box"><p><p> G型單螺桿泵螺桿軸磨損原因分析，G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個(gè)理想塑化的加工溫度范圍，應(yīng)該控制料筒加工溫度，使之接近這個(gè)溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會(huì)到達(dá)加料段，在加料段必然會(huì)出現(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時(shí)，很易造成料筒內(nèi)壁及螺桿表面磨損增大。同樣，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會(huì)造成磨損增快。2，揭陽螺桿泵高質(zhì)量的選擇、轉(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強(qiáng)化劑，如玻璃纖維，揭陽螺桿泵高質(zhì)量的選擇、礦物質(zhì)或其他填充料。這些物質(zhì)對(duì)金屬材質(zhì)的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時(shí)，如果用高的轉(zhuǎn)速成，揭陽螺桿泵高質(zhì)量的選擇，則在提高對(duì)塑料的剪切力的同時(shí)，亦將令強(qiáng)化相應(yīng)地產(chǎn)生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機(jī)礦物質(zhì)在金屬表面高速滑行時(shí)，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。

為了保證螺桿泵的安全運(yùn)行，在螺桿泵啟動(dòng)前，應(yīng)對(duì)整個(gè)機(jī)組作***的檢查，發(fā)現(xiàn)問題，及時(shí)處理。檢查內(nèi)容有以下幾項(xiàng)，（1）電動(dòng)機(jī)和水螺桿泵固定是否良好，螺釘及螺母有無松動(dòng)脫落； </p> <p> <br /> </p> <p> （2）檢查各軸承的潤滑油是否充足，潤滑油是否變質(zhì)； </p> <p> <br /> </p> <p> （3）如果是***次使用或重新安裝的水螺桿泵，應(yīng)檢查水螺桿泵的轉(zhuǎn)動(dòng)方向是否正確； </p> <p> <br /> </p> <p> （4）檢查吸液池及濾網(wǎng)上是否有雜物； </p> <p> <br /> </p> <p> （5）檢查填料箱內(nèi)的填料是否發(fā)硬； </p> <p> <br /> </p> <p> （6）檢查排液管上的閥門啟閉是否靈活； </p> <p> <br /> </p> <p> （7）檢查電動(dòng)機(jī)的電氣線路是否正確； </p> <p> <br /> </p> <p> （8）檢查機(jī)組附近有無妨礙運(yùn)轉(zhuǎn)的物體。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 梅州螺桿泵服務(wù)商在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揭陽螺桿泵高質(zhì)量的選擇,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900322265/6521222.jpg"></div><p> 4、拆卸轉(zhuǎn)子、連桿、短節(jié)、密封盒先卸下三通。卸去鋼絲卡圈或緊定螺釘。退出圓柱銷防落套后，取下圓銷。接下來可分離轉(zhuǎn)子、連桿、短節(jié)、傳動(dòng)軸等零件。卸下短節(jié)后，即可取出密封盒。對(duì)采用機(jī)械密封的，則要非常小心翼翼地進(jìn)行，否則極易造成動(dòng)、靜環(huán)的破碎。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 5、重新裝泵前，應(yīng)做好各項(xiàng)更換、維修的準(zhǔn)備工作。嚴(yán)格檢查待裝零件的質(zhì)量，清洗是否干凈，外表是否損壞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 6、裝配步驟正好與拆卸步驟相反。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 7、在裝配填料密封時(shí)，注意調(diào)整不要過緊。待試車進(jìn)料后逐步壓緊，以介質(zhì)略有滴漏為宜。如機(jī)械密封。則應(yīng)注意動(dòng)、靜環(huán)上無雜質(zhì)，并涂上潤滑脂。靜環(huán)必須平整地裝手密封盒。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 8、連桿節(jié)頭處應(yīng)檢查橡膠護(hù)套是否損壞。在空腔內(nèi)是否充滿潤滑脂。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 9、安裝定子時(shí)，橡膠表面涂以潤滑脂(包括轉(zhuǎn)子)，有利于安裝及試運(yùn)轉(zhuǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> </p><p> 但是其缺點(diǎn)也是非常明顯：加工精度要求更高，增加了加工的難度，特別是加二精度不夠就會(huì)影響轉(zhuǎn)子和定子的配合均勻度，使上述的第4)、5)和6)點(diǎn)優(yōu)點(diǎn)不再存在；而且加工工時(shí)多和生產(chǎn)成本較高，這就是目前生產(chǎn)較少的原因。 </p> <p> <br /> </p> <p> 當(dāng)然，也可以制造轉(zhuǎn)子和定子螺旋頭數(shù)更多的單螺桿泵，如三頭螺旋的轉(zhuǎn)子和四頭內(nèi)螺旋定子構(gòu)成的泵等，但對(duì)制造精度的要求更髙，且流量并不是總隨螺旋頭 </p> <p> <br /> </p> <p> 增加而增大，故已無多少實(shí)際意義。雖然這種更多螺旋頭數(shù)的轉(zhuǎn)子和定子的嚙合副在單螺桿泵中并沒有得到應(yīng)用，但在石油機(jī)械的螺桿鉆具這一領(lǐng)域卻得到了***的應(yīng)用。 </p> <p> <br /> </p> <p> <br /> 單螺桿泵體積小，重量輕、噪聲低，結(jié)構(gòu)簡單，維修方便.</p><div

②流道寬，可以輸送含有固體物的水。 </p> <p> ③泵體結(jié)構(gòu)是半開的，可以觀察到泵內(nèi)的運(yùn)行情況。 </p> <p> ④吸入側(cè)流態(tài)對(duì)水力性能影響甚微，對(duì)吸水池?zé)o特殊要求，基礎(chǔ)開挖深度小，水工建筑物施工簡單，土建費(fèi)用少。 </p> <p> 其缺點(diǎn)是： </p> <p> ①尺寸大，占地面積也大。 </p> <p> ②受機(jī)械加工條件限制，泵軸不能太長，因而揚(yáng)程較低，一般不超過10m。 </p> <p> ③吸水面、出水面高度變化不能太大，否則會(huì)影響工作效率，增加能耗。 </p> <p> <br /> 重新裝泵前，應(yīng)做好各項(xiàng)更換、維修的準(zhǔn)備工作。***螺桿泵批發(fā)廠家</p><p
